51c370dc24 Instead of clearing, prevent filling filename input in Open dialog 
Prevent the filename input from being populated in the first place,
instead of resetting after its unintentionally populated when the
directory tree is expanded.

Nip it in the bud. Head it off at the pass. Stop it at the source.

It still needs this new flag to be cleared on a timer, but at least this
timer is near the code for the other timers it needs to trigger after.

Explicitly set filename for Save As dialog, which SHOULD be populated.

c659418240 Clean up attempt at more optimal color inverting 
I don't want to bother importing Rich's Color class in addition to
Textual's Color class.

This also doesn't work, which might be the fastest if it worked:

    style.color.triplet.red = 255 - style.color.triplet.red
    style.color.triplet.green = 255 - style.color.triplet.green
    style.color.triplet.blue = 255 - style.color.triplet.blue
    style.bgcolor.triplet.red = 255 - style.bgcolor.triplet.red
    style.bgcolor.triplet.green = 255 - style.bgcolor.triplet.green
    style.bgcolor.triplet.blue = 255 - style.bgcolor.triplet.blue

5e994fbc91 Move command line argument parsing to the top 
This will make it possible to load localization data for a language
defined by a command-line argument, throughout the program.

Unfortunately this separates the usage of the arguments from their
definitions by a wide margin, making it harder to edit, especially
with AI autocomplete. For now. I could refactor things, either move
the bulk of this file to separate files, or define a configure_app
function up top to use down below.

  This is my first time using asynchronous features in Python,
  (as far as I remember,) so it's a bit messy.
- Make DialogWindow callback also for Cancel, which means all
  DialogWindow usage sites care what button is selected.
- Send RequestClose event for Esc key.

cb6b4403a3 Handle passing arguments via textual run 
It took a while to figure out this magic.

`textual run --help` says:

>  If you are running a file and want to pass command line arguments, wrap the
>  filename and arguments in quotes:
>
>      textual run "foo.py arg --option"

But it doesn't describe how to handle those arguments.

da3d3b0f06 Rename Save As dialog IDs to match Open dialog IDs 
It's a bit verbose, but for Open, I wanted the _dialog part since "open"
can be both a verb and an adjective, and I didn't like it reading as an
adjective. It doesn't technically disambiguate it, but it reads better.

Verb "[to] open", noun "[dialog to] open", adjective "[part of the dialog to] open"
Adjective "[is] open", noun "[dialog that is] open", adjective "[part of the dialog that is] open"

Anyways this commit just makes it consistent.
Perhaps I could use classes more in place of IDs.

ad111e5d6c Refactor: extract tool handling from Canvas 
I wanted to avoid duplicating tool-related state between PaintApp and
Canvas, and prepare for adding different tools with more state and which
will want to live in a separate file.

This makes it slower, when running with `textual run --dev paint.py`;
when running with `python3 paint.py`, it's fine.
When running in dev mode with `textual console` devtool connected, it's
extremely much slower. But if it was faster, you'd have more messages
to scroll through, ha. So it's a tradeoff.*
*Ideally you want it to be fast and for the logs to be compacted.

In the future, I could bypass the message system for performance, but
for now I think it's better to stay idiomatic.
